Book One: Air

The first chapter in The Legend of Korra, which includes episodes 1-12. This season aired from April 14, 2012 until June 23, 2012. Set 70 years after the events of Avatar: The Last Airbender, this spin-off series introduces Korra, the next Avatar after Aang. Unlike her predecessor, however, Korra has already mastered the elements of water, earth and fire by the start of the series. All that remains is airbending, which she'll have to learn from Aang's son Tenzin in Republic City, the capital of the Four Nations.
